A SURVEY OF STUDIES IN SUPPORT OF
REPRESSED MEMORIES, WITH REBUTTALS

Sponsored link.

The original article, and a rebuttal:

Brown, Scheflin & Whitfield wrote an article in the Journal of Psychiatry
& Law in support of the existence of repressed memories being caused by traumatic events.
This is an important report, because such repression must happen often if
Recovered Memory Therapy (RMT) is to have any validity. They concluded that the studies that they had
analyzed from many countries around the world give support to the reality of
memory repression (a.k.a. dissociative amnesia). 1

Piper, Pope & Borowiecki wrote a followup article in the same journal
analyzing the study by Brown et al., and concluding that none of the studies
examined support memory repression. 2

Nine claims of memory repression, with rebuttals:

Assertion by Brown, et al.

Rebuttal by Piper et al.

A study by Cardena & Spiegel states that they found amnesia
in 3 to 5% of the most severely affected group.

No such statement exists in the Cardena & Spiegel report

Two of 38 victims of lightning suffered amnesia.

The boys received the equivalent to an Electroconvulsive
Treatment (ECT), which is known to damage the brain and thus produce simple
biological amnesia. This is unrelated to RMT, and repressed memories.

In a study of flash flood survivors, some suffered from
amnesia.

No evidence is provided in the report that indicates that
any of the victims actually forgot the tragedy itself -- the flash flood.

In another study of flood survivors, 7% of the children
could not recall parts of what had happened.

Some of the children were as young as 2 years of age -- an
age at which children are incapable of having long-term memories.

In a pipeline disaster, a report showed that more of the
victims suffered amnesia than did a control group.

No evidence is provided in the report that indicates that
any of the victims actually forgot the actual event.

Among older children of an earthquake, 32% suffered amnesia

49 of the 50 children had symptoms of "re-experiencing" the
earthquake, including "intrusive recollections" in 46 of the 49. There is no
evidence that any child forgot the actual earthquake.

Some child survivors of the Nazi holocaust are troubled by
memories -- either too much or too little.

The original quotation referred mainly to young children who
had lost their parents to the Holocaust when the children were very young.
Thus one would expect them to have few, if any, memories of their parents. There is
no evidence that any subject forgot their involvement in the Holocaust.

A study of Norwegian camp survivors indicated that 78%
suffered from loss of memory or failing memory.

The report actually reports that 78% of the survivors
suffered failing memories, not lost memories.

A study of Bosnian refugees found that 20% suffered amnesia

Only four subjects were involved. Three of them reported
amnesia "once a week or less, a little bit, once in a while." One had
amnesia "2-4 times per week, somewhat." No victim had
continuous amnesia of the ethnic cleansing.

As a minimum, it would seem that the assertions by Brown et al. are not
supported by the original studies that they quote. One can conclude that the
existence of memory repression brought about by serious emotional or physical
trauma is not supported by their report.
